Services Stairwell Pressurisation
Australian legislations require the building owner to provide annual proof of compliance for essential safety measure to operate in an emergency situation by ensuring the performance of the Annual System Interface Testing.
Why is this necessary?
The Building Code of Australia in Part E2 Smoke Hazard Management in clause E2.2 General requirements stipulates compliance with Table E2.2a General Provisions which requires any fire-isolated stairway to be provided with stairwell pressurisation – an automatic air pressurisation system. The BCA requires a stairwell pressurisation system to ensure the occupants of a building in a fire emergency have sufficient time to evacuate the building before the stairwell becomes untenable. A stairwell pressurisation system must be installed in accordance with AS/NZS 1668.1:1998 The use of ventilation and air-conditioning in buildings – Fire and smoke control in multi-compartment buildings and the building permit. When installed, the stairwell pressurisation system will be in Normal Mode and Fire Mode (if needed). In the event of a fire detection system detecting a fire in the buildings, the stairwell pressurisation system will automatically change to fire mode and start the system.
